Thread Locker Loc Tite by Bob Smith Industries is extremely useful stuff. I use this on flywheel cage screws to avoid the potential for them to vibrate loose and cause damage to your flywheels and cage (This has happened to me at least a half dozen times now). Bob Smith Industries offers a great selection of high-quality glue products.
-Use to lock your flywheel screws in place
-Plastic safe for contact but NOT recommended for holding any plastic parts together in any way
